Eda Church is a supporting character in the anime and manga series Black Lagoon. She is a sharp-tongued, quick-witted nun who works at the Rip-Off Church in Roanapur, which serves as both a sanctuary and a front for illegal activities. Eda is known for her laid-back attitude, mischievous sense of humor, and secretive nature. Despite her religious façade, she is involved in arms dealing and has a mysterious connection to the CIA. Eda often interacts with Revy and the Lagoon Company, sometimes as an ally and sometimes as a manipulator.
